Madonna greeted British fans with a raunchy performance at London's Hyde Park as she returned to stage in the UK with her MDNA tour.
The 53-year-old, who is no stranger to controversy, stunned fans as she undressed down to a sheer bra to expose a No Fear tattoo on her back while singing a stripped-back version of her hit Like A Virgin.
Her boyfriend and backing dancer Brahim Zaibat, 24, then fastened a corset around her.
"I like to live dangerously," she said.
Madonna has so far shocked audiences on other legs of her MDNA world tour. In Turkey, she pulled down her bra and flashed her breast on stage, while singing Human Nature, and In Rome she pulled down her trousers in front of fans.
Her Paris gig angered France's far-right National Front after the singer showed a video that contained an image of the party's leader with a swastika on her forehead.
Her return to stage marked her first performance in the UK in four years since her Sticky And Sweet tour in 2009.
As she performed in front of around 50,000 fans, Madonna made sure she did not fall foul of the authorities by finishing her show minutes before the 10.30pm curfew.
The curfew saw Bruce Springsteen cut short at his Hyde Park performance on July 14 when he overran during a rendition of the Beatles' hit Twist And Shout.
Madonna, previously married to British film-maker Guy Ritchie, also introduced her 11-year-old son Rocco, who joined her as a dancer on stage.
She performed tracks from her latest album MDNA as well as classic favourites like Papa Don't Preach, Hung Up and Vogue - and even took a pop at music rival Lady Gaga by incorporating a rendition of Gaga's Born This Way during Express Yourself.
Madonna, who was supported by US electro-pop duo LMFAO and French DJ-producer Martin Solveig, brandished two guns on Revolver and Gang Bang and joked about the weather when it began to rain.
"Everybody, say your prayers to make the rain go away," she quipped.
Her MDNA tour was due to stop off in Birmingham on Thursday, July 19, and Edinburgh on Saturday July 21.
